Key actives

Heptasodium Hexacarboxymethyl Dipeptide-12peptide

A two-amino-acid peptide with carboxymethyl groups added, which makes it strongly water soluble. It is used for the look of uneven tone. On this serum's own ingredient list it is named seventeenth.

Ceramide NPbarrier lipid

Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy. The panel names it eighteenth on this serum's list, beside Heptasodium Hexacarboxymethyl Dipeptide-12.

Ceramide NSbarrier lipid

Ceramide NS is another of the ceramides skin makes for itself. It is used alongside NP and AP so a formula supplies a mixture rather than a single lipid. The panel names it twenty-second on this serum's list, beside Heptasodium Hexacarboxymethyl Dipeptide-12.

Ceramide ASbarrier lipid

Ceramide AS is a further member of the same lipid family. Its presence usually signals a formula built around a full ceramide profile rather than a single headline one. The panel names it twenty-third on this serum's list, beside Heptasodium Hexacarboxymethyl Dipeptide-12.

Ceramide APbarrier lipid

Ceramide AP is a second cosmetic ceramide, distinguished by an extra hydroxyl group. Formulas that name several ceramides are copying the mix skin actually holds rather than relying on one. The panel names it twenty-fourth on this serum's list, beside Heptasodium Hexacarboxymethyl Dipeptide-12.

How to use

  1. Smooth two to three drops over cleansed and toned skin morning and evening, patting gently until absorbed before a moisturizer.

How it works

The Dual Barrier Boosting Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The peptide it is built around is Heptasodium Hexacarboxymethyl Dipeptide-12, named seventeenth on its own ingredient list. The same list carries Ceramide NP, Ceramide NS and Ceramide AS, so the peptide is not the only thing on it worth naming. How much of the Heptasodium Hexacarboxymethyl Dipeptide-12 stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum Celimax sells in Korea, Heptasodium Hexacarboxymethyl Dipeptide-12 and all.

Worth knowing

  • Patch test this serum on a small area and wait a day before using it more widely, especially with Heptasodium Hexacarboxymethyl Dipeptide-12 on the list.
  • Introduce this serum on its own for the first week, so anything your skin does is traceable to the Heptasodium Hexacarboxymethyl Dipeptide-12 rather than to three changes at once.

  • Peptides can be anti-inflammatory, and chronic inflammation damages the tissue in your skin.

  • Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.
